Audio Driver Problem

[anagh.k1]

this my pc configuration:
amd phenom II x4 955
ati radeon 5450
biostar ta485g3 hd.

there is no soundcard installed.

i have windows xp 32-bit professional edition installed.

suggest a good audio driver pack.

i tried realtek ac97 audio driver but it doesn't work.

i also tried reltek high definition audio driver v248 pack but sound comes from only the speakers.it dosen't detect headphones so sound dosen't come from headphones.(any solution?)

i am thinking of trying ati radeon hd 5450 ati hdmi audio driver 10.5 pack.

Realtek Hidh Definition Audio driver is actually the driver which you should be using. *www.biostar.com.tw/app/en/t-series/driver.php?S_ID=436

Are you sure that you have plugged your headphone in the right jack?
